| 摘 要： | 针对目前全景漫游系统漫游在切换视点过程中产生跳跃感的问题提出了一种实用的全景漫游算法。该算法以摄影变焦原理为基础，结合人机工程学视觉原则方面的理论，通过对观察摄像机朝向和视角的操作模拟视点的运动过程，实现漫游效果。漫游过程避免了复杂的图像变换运算，有很好的实时性。并且创建了一个运用该算法控制全景漫游的X3D场景，实验验证了该算法的可行性。

| Abstract: | An applied navigation algorithm account for the full view navigation system cannot transit from one viewpoint to another in a smooth way. The algorithm based on zoom lens principle in photog- raphy and combined with vision principle in Man-Machine Engineering. It implements navigation by control the dummy camera＇ s orientation and field of view. Navigation process avoids complicated view interpolation and morphing, so it can respond in real time. Then compiled an X3D program of full view navigation include this algorithm, validated this algorithm＇s feasibility by experiment. |
